# Validator Node Pool Deployment
|
||
|
||
## Configuration
|
||
|
||
### Validator Nodes
|
||
- **Count**: 2 nodes
|
||
- **VM Size**: Standard_B1ms
|
||
- **vCPUs**: 1 per node (2 total)
|
||
- **Memory**: 2GB RAM per node (4GB total)
|
||
- **Type**: Burstable (B-series)
|
||
|
||
### Resource Summary
|
||
- **System Pool**: 3 × Standard_D2s_v3 (2 vCPUs, 8GB RAM each) = 6 vCPUs
|
||
- **Validator Pool**: 2 × Standard_B1ms (1 vCPU, 2GB RAM each) = 2 vCPUs
|
||
- **Total**: 8 vCPUs (within 10 vCPU limit) ✅
|
||
|
||
## Standard_B1ms Specifications
|
||
|
||
### Compute
|
||
- **vCPUs**: 1
|
||
- **Memory**: 2GB RAM
|
||
- **Burstable**: Yes (CPU credits)
|
||
- **Cost**: ~$0.0104/hour (~$7.50/month per node)
|
||
|
||
### Storage
|
||
- **OS Disk**: Up to 32GB (Premium SSD)
|
||
- **Data Disks**: Up to 2 disks
|
||
- **Max IOPS**: 1,920 IOPS
|
||
|
||
### Network
|
||
- **NICs**: 2 network interfaces
|
||
- **Bandwidth**: Moderate (up to 200 Mbps)
|
||
|
||
## Why Standard_B1ms for Validators?
|
||
|
||
### Advantages
|
||
1. **Fits Quota**: 1 vCPU allows 2 validators within 4 available vCPUs
|
||
2. **Cost Effective**: 90% cheaper than Standard_D2s_v3
|
||
3. **Sufficient for Besu**: 1 vCPU, 2GB RAM meets minimum requirements
|
||
4. **Burstable**: CPU credits for variable workloads
|
||
5. **Scalable**: Can upgrade to Standard_B2s or Standard_D2s_v3 later
|
||
|
||
### Considerations
|
||
- **CPU Credits**: B-series uses burst credits, monitor usage
|
||
- **Performance**: May need upgrade for high-volume production
|
||
- **Memory**: 2GB RAM is minimal, may need upgrade for large states
|
||
|
||
## Deployment Status
|
||
|
||
### Before Deployment
|
||
- **System Nodes**: 3 × Standard_D2s_v3 = 6 vCPUs
|
||
- **Total**: 6 vCPUs
|
||
|
||
### After Deployment
|
||
- **System Nodes**: 3 × Standard_D2s_v3 = 6 vCPUs
|
||
- **Validator Nodes**: 2 × Standard_B1ms = 2 vCPUs
|
||
- **Total**: 8 vCPUs (within 10 limit) ✅
|
||
|
||
## Monitoring
|
||
|
||
### Check Validator Nodes
|
||
```bash
|
||
# View node pool status
|
||
az aks nodepool show \
|
||
--resource-group az-p-we-rg-comp-001 \
|
||
--cluster-name az-p-we-aks-main \
|
||
--name validators
|
||
|
||
# View all nodes
|
||
kubectl get nodes -o wide
|
||
|
||
# Check node resources
|
||
kubectl top nodes
|
||
```
|
||
|
||
### Monitor CPU Credits (B-series)
|
||
```bash
|
||
# Check Azure Monitor metrics
|
||
az monitor metrics list \
|
||
--resource /subscriptions/fc08d829-4f14-413d-ab27-ce024425db0b/resourceGroups/az-p-we-rg-comp-001/providers/Microsoft.ContainerService/managedClusters/az-p-we-aks-main \
|
||
--metric "Percentage CPU Credits Remaining"
|
||
```
|
||
|
||
## Next Steps
|
||
|
||
1. **Deploy Besu Validators**: Deploy Besu pods to validator nodes
|
||
2. **Monitor Performance**: Check CPU credits and performance
|
||
3. **Scale Up**: Upgrade to Standard_B2s if needed
|
||
4. **Deploy Sentries**: After quota increase or optimization
|
||
|
||
## Upgrade Path
|
||
|
||
### If Performance is Insufficient
|
||
- **Option 1**: Upgrade to Standard_B2s (2 vCPUs, 4GB RAM)
|
||
- **Option 2**: Upgrade to Standard_D2s_v3 (2 vCPUs, 8GB RAM)
|
||
- **Option 3**: Increase node count (need quota increase)
|
||
|
||
### Cost Comparison
|
||
- **Standard_B1ms**: ~$7.50/month (current)
|
||
- **Standard_B2s**: ~$15/month (2× cost, 2× vCPUs)
|
||
- **Standard_D2s_v3**: ~$70/month (9× cost, 2× vCPUs)
